Product Core Advantages
1. Precise Temperature Resistance with Extreme Stability
Our gradient fiber composite technology ensures exceptional stability across a wide temperature range of 800–1400°C. The thermal expansion coefficient is 30% lower than industry standards, and high-temperature linear shrinkage is controlled within 1.5%. Even under rapid heating and cooling cycles, structural integrity is maintained, significantly extending service life.
2. Customization Freedom and Complex Forming
Featuring an industry-leading digital molding system for shaped components, we support full digital customization from 3D scanning to reverse engineering. We can precisely manufacture complex geometric structures such as curved surfaces, porous designs, and irregular cavities, with dimensional accuracy up to ±0.3mm. This ensures "design-to-reality" outcomes that perfectly match your equipment contours.
3. Intelligent Insulation with Significant Energy Savings
Our proprietary multi-pore gradient structure design reduces thermal conductivity to as low as 0.08 W/(m·K), achieving over 40% energy savings compared to traditional materials. Intelligent thermal resistance distribution technology focuses protection on high-temperature areas, improving surface temperature uniformity by 50%, significantly reducing energy consumption and operational costs.
4. Exceptional Toughness and Strength
Through fiber directional alignment enhancement and nano-interface strengthening technology, the flexural strength of our products exceeds 3.5 MPa-1.8 times that of similar products. The unique internal layered reinforcement structure ensures the shaped components maintain outstanding structural integrity even under dual challenges of mechanical load and thermal stress.

FAQ
Q1: What is the service life of inorganic fiber shaped components?
A1: The service life depends on operating temperature, atmospheric conditions, and mechanical load. Under normal operating conditions, our products typically last 1–5 years. In lower-temperature (<1000°C) and stable environments, the service life can exceed 5 years. In higher-temperature or harsher environments, regular inspections and replacements based on actual conditions are recommended.
Q2: What shapes and sizes can be customized for the product?
A2: We can customize various complex shapes based on customer drawings or samples, including curved surfaces, irregular holes, and composite structures. The maximum processing dimensions are 1200×800×300mm. Larger components can be manufactured in segments for combined installation. The smallest detail feature size achievable is 2mm.
Q3: What should be noted during product installation?
A3: During installation, please note: 1) Handle with care to avoid impact; 2) Ensure the installation surface is clean and level; 3) Allow appropriate gaps for thermal expansion; 4) Use specialized high-temperature adhesives or mechanical fasteners; 5) For multi-layer installation, stagger the joints. We provide detailed installation guidelines and technical support.
Q4: How does the product differ from ceramic fiber products?
A4: Our inorganic fiber shaped components are made from a composite of multiple inorganic fibers, offering better thermal shock resistance, lower thermal conductivity, and higher strength compared to single-material ceramic fiber products. Additionally, we can adjust the formulation based on specific applications to achieve optimized performance combinations.
Q5: How to select the appropriate density and thickness?
A5: Selection is primarily based on: 1) Operating temperature; 2) Permissible heat loss; 3) Installation space constraints; 4) Mechanical load requirements. We offer free technical consultation to recommend the most suitable density and thickness combination based on your specific working conditions.
Q6: Does the product comply with environmental and safety standards?
A6: Yes. The product is made from 100% inorganic raw materials, free from asbestos and harmful volatile compounds. The production and application processes are safe and environmentally friendly, complying with international standards such as EU RoHS and REACH.
